鋼拱架軸力主要為壓力,僅在拱頂和拱腳等較少部位出現(xiàn)拉力。下臺階邊墻開挖之前,鋼拱架各部位軸力為負(fù)值,均處于偏心受壓狀態(tài);下邊墻開挖后,拱頂軸力變?yōu)槔?,分析認(rèn)為下臺階邊墻的開挖,造成鋼拱架底部懸空,使鋼架在上部圍巖壓力和側(cè)壓力的合力作用下,發(fā)生下沉和向臨空面收斂變形兩種運動趨勢,致使拱頂鋼架出現(xiàn)受拉的情況。</span>

格柵拱架施工是具有結(jié)構(gòu)簡單、用鋼量少、受力結(jié)構(gòu)條件好、加工制造方便、架設(shè)工藝簡單等優(yōu)點,對于軟弱破碎圍巖加強地段的施工和處理險情、坍方處理都是一種能應(yīng)急而有效的施工措施和手段。</span>

資料統(tǒng)計,工程滲水70%是因施工縫處理不當(dāng)造成的,工程滲水造成施工作業(yè)差,無形中了施工難度,嚴(yán)重影響施工進(jìn)度。滲水會對圍巖進(jìn)行侵蝕,使圍巖性,沖掏襯砌背后圍巖形成空洞,威脅襯砌。在階段,滲水會加快內(nèi)部結(jié)構(gòu)的銹蝕,影響結(jié)構(gòu)的受力,長期滲水容易使襯砌剝落、風(fēng)化,的使用可靠性;若含有侵蝕介質(zhì),將造成襯砌劣化,襯砌的承載能力。</span>

格柵鋼架各組成部件焊接完成后,進(jìn)行試拼裝,以檢驗格柵鋼架的幾何尺寸,各部件的螺栓節(jié)點以及焊接等。首榀試拼合格后,進(jìn)行驗收,而后進(jìn)行批量生產(chǎn),并按規(guī)定抽樣進(jìn)行批量驗收。</span>
